Whatever his appearance, he was not an attractive man.
Isa 53:1-3
Who has believed our message
and to whom has the arm of the LORD been revealed?
2 He grew up before him like a tender shoot,
and like a root out of dry ground.
He had no beauty or majesty to attract us to him,
nothing in his appearance that we should desire him.
3 He was despised and rejected by men,
a man of sorrows, and familiar with suffering.
Like one from whom men hide their faces
he was despised, and we esteemed him not.
And ironically He attracted a huge enough following that the religious leaders of His time considered Him a real threat.
Well, yes and no.
Christ was not physically attractive to those in His own time, even as Isaiah prophesied--particularly at the time of His Passion to which that section of Isaiah points. However, I think Christendom's notion of what is attractive in a man's visage, has somewhat adapted to Him.
